writing a special character in sed bash

Question

I have a problem, because I want to replace

QueryConnection::DefaultChannel=

with

QueryConnection::DefaultChannel=/${CHANNEL NUMBER}

e.g: QueryConnection::DefaultChannel=/5

My code:

sed -i "s/QueryConnection::DefaultChannel=.*/QueryConnection::DefaultChannel=${NUMER_KANALU}/" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"

How to make before ${NUMER_KANALU} be "/"?

Two choices:

Escape the slash:

sed -i "s/QueryConnection::DefaultChannel=.*/QueryConnection::DefaultChannel=\/${NUMER_KANALU}/" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"

Use a different delimiter around the s parameters:

sed -i "s#QueryConnection::DefaultChannel=.*#QueryConnection::DefaultChannel=/${NUMER_KANALU}#" "${DIR_BOTS}/bot_${COUNT_BOTS}/configTS3AudioBot.cfg"
